How to Share Your Screen / Cast Display on Windows 11

Mirror or extend your screen to a TV, monitor, or video call.

Last verified: February 21, 2026

Windows supports wireless display casting to any Miracast or DLNA-compatible receiver through the Cast panel, opened with Windows + K. This works with smart TVs, Chromecast devices, Amazon Fire Sticks, and Miracast adapters plugged into any HDMI port — no Apple TV required. Windows also lets you choose between Duplicate (mirror exactly), Extend (use the TV as a second monitor), or Second screen only modes, giving you more flexibility than many mobile casting solutions.

Quick Steps

Follow in order for the fastest result.

  1. 1Press Windows + K to open the Cast panel. Ensure both devices are on the same Wi-Fi. Select your TV or external monitor from the list.
  2. 2Wait 5–10 seconds for the connection to establish and the display to mirror.
  3. 3Adjust display mode (Mirror vs Extend) in Display Settings after connecting if available.

Frequently Asked Questions

How do I cast my Windows 11 screen to a TV?
Press Windows + K to open the Cast panel. Both your PC and the TV (or Chromecast/Fire Stick) must be on the same Wi-Fi network. Select the display from the list.
Why can't I see my TV in the cast list on Windows 11?
The most common cause is that the two devices are on different networks — for example, your device is on a 5 GHz band and the TV is on 2.4 GHz, or one is on a Guest network. Ensure both are on the exact same Wi-Fi network. Also restart both the casting device and the receiver.
Can I share only one app instead of the whole screen on Windows 11?
Yes. In the Cast panel, you can choose between Duplicate (mirror), Extend, or Second screen only modes. For app-specific sharing in video calls, use the app's built-in screen share feature instead.
Does screen casting drain battery faster on Windows 11?
Yes — wireless casting keeps the display on, Wi-Fi active, and the GPU encoding continuously, which increases battery drain noticeably. For extended sessions, keep the device plugged in.
